2Claims. orzoe- -iss) I must be supported so as to prevent them from rubbingagainst each other or against the walls of the carton in which they-are eontained, since such rubbing ;would damage at-least the outer 'layers of yarn on'said packages, The cartons heretofore employed for j storing and shipping yarn packages havedncludedineans, such as apertured inserts, for engaging the yarn packages so as to prevent movement thereof and damage to the yarn wound thereon. However, these cartons have been relatively expensive and have required a considerable amount of labor for their assembly and disassembly, thereby increasing the handling costs in storing and shipping the yarn packages. In addition, these cartons have failed to provide adequate support for the yarn packages, with the result that yarn damage frequently occurred, particularly when ages of yarn which will be free from the foregoing and other disadvantages of the cartons hi therto employed for this purpose, and which W111 be especially simple in construction and efiicient in use.

A further object of this invention is the provision of a carton for storing and shipping packages of yarn which'willengage and support said packages so as to avoid relative movement thereof and, damage to the yarn wound thereon.

Other objects of this invention, together with certain details of construction and combinations of parts, will be apparent from the following detailed description and claims.

A preferred embodiment of our invention of a carton for storing and shipping cones of yarn will now be described with particular reference to the accompanying drawing wherein Fig. 1 is a cross-sectional view of the carton showing the arrangement of the packages of yarn therein,

Fig. 2 is a cross-sectional view taken on the line 2- 2 in Fig. 1 in. the direction of the arrows,

Fig. 3 is a detail view, on an enlarged scale, showing the manner in which the packages of yarn are supported, and

t is 'a perspective view, on an enlarged scale, showing the fitting that engages the pack-' agesof, yarn. Y 7

Referring now to the drawing, the reference numeral .II designates generally the protective cover of a carton which may be formed from corrugated board, cardboard or other suitable material and. in which is contained a plurality of yarn packages, such as cones I2 comprising tubes I3 ofconical shape having yarn I4 wound thereon; The cones I2 are arranged in superposed layers I5, I9, I1 and I8, each of which layers issupported on a shelf 'I9 having aplu rality'of regularly disposed'apertures 22 extending .therethrough. Positioned in the apertures 22 are fittings, indicated generally by reference numeral 23, comprising a base 24 having a rounded nipple 25 projecting from the under surface of said base and extending through the apertures 22, which nipple 25 is of such diameter as to engage snugly the top of the tube I3. An

inwardly tapering wall 26, which is of such diameter and inclination as to engage snugly the base of the tube I3 projects from the periphery of the upper surface of base 24. The shelves I9 and the fittings 23 are each formed from a suitable organic plastic material such as, for example, cellulose acetate or other organic acid ester of cellulose and are joined together by means of a cement containing a solvent for the organic plastic material to form a strongautogenous bond. Because of the strength of the plastic material from which the shelves I9 and the fittings 23 are formed and because of the strength of the autogenous bond between said members, the shelves I9 may be reused repeatedly, thereby decreasing the cost of the cartons.

In packing the carton of our invention, the cones I2 are positioned on the shelves I9 with the base of the tube I3 of each of said cones snugly engaging the wall 26 of a fitting 23 to hold said cones against relative movement and damage to the yarn thereon. Then the shelf I9 with the cones l2 thereon is placed in the protec-' tive cover I I, forming the layer indicated by reference numeral I5, with the nipples 25 of said shelf resting on a liner 2! in said protective cover. A second shelf I9 with cones I2 thereon is then placed in the protective cover II to form the layer I6 with the nipples 25 of said shelf fitting snugly into the tops of the tubes I3 of the cones I2 inthe layer I5. The layers I1 and I8 are formed and superposed on the layer I6 in similar manner, On top of the layer I8, there is placed a shelf I9, with the nipples 25 of said shelf Having described our invention, what we desire to secure by Letters Patent is:

1. In a carton for storing and shipping superposed layers of yarn packages having conical cores, the combination with apertured shelves,

of an organic derivative of cellulose, each' adapted to support a layer of yarn packages, of fittings, of an organic derivative of cellulose, extending through the apertures in said shelves and being cemented thereto form an autogenous bond for engaging said yarn packages to prevent relative movement thereof, said fittings comprising a downwardly extending nipple for reception Within the top of the conical core of the yarn package positioned on a shelf beneath the shelf having said fittings therein and, integral with said nipple, an upwardly extending inwardly-tapered, cup-shaped portion of greater diameter than said nipple for reception within the bottom of the conical core of a yarn package positioned on the shelf having the fittings therein. g

2. In a carton for storing and shipping superposed layers of yarn packages having conical cores, the combination with apertured shelves, of cellulose acetate, each adapted to support a layer of yarn packages, of fittings, of cellulose acetate, extending through the apertures in said shelves and being cemented thereto to form an autogenous bond for engaging said yarn packages to prevent relative movement thereof, said fittings comprising a downwardly extending nipple for receptionwithin the top of the conical core of the yarn package positioned on a shelf beneath theshelf having said fittings therein and, integral with said nipple, an upwardly extending inwardly tapered, cup-shaped portion of greater diameter than said nipple for reception within the bottom of the conical core of a yarn package positioned on the shelf having the fittings therein.
